I have to ask, with the stock 75amp alternator (with the 4cyl), do you have any problems running accesories while the fan kicks on? such as lights or the heater or a winch?

my worries about my alternator have been the only thing stopping me from doing the taurus fan mod.

I believe the stock alternator is 90 amps. But if your concerned, check out the link below. This was the easiest mod I have ever done to the Jeep.

Oh and I have only ever had to run high speed twice. Both times the Jeep was fully loaded and it was a steep incline.

does the electric fan push air or pull air?
What does the stock mechanical fan do, push or pull?
Thanks,
Vance

They pull air like any other fan?

I put a 4.0TB in at about the same time as I put the fan in a couple months ago and it works great. I know for a fact that I have more pep off of the starting line and it accelerates quicker as well. I have the 70Amp alternator and the guage always reads with the needle at the center, so it seems to be plenty to run the fan on low. (The needle twitches when I turn the fan on but goes right back to normal)

Now, I wired the fan to my ignition so it only runs when the key is in the "On" position. I also put in a toggle switch so that I can kill the fan when I go underwater, or while I'm on the highway (I noticed that just driving 60-70mph keeps my engine cool enough without the fan on even in summer! ).



I'm going to climb some hills tomorrow that I haven't done since before the fan/TB mods. Can't wait to see if it climbs easier!

I have a sable fan, the shroud has a kind of ">" shape on it. It is too thick to fit my 4.2L between the radiator & bolted pulley. I'm thinking the one pictured might be a little bit thinner.

Anyone do this mod to a 4.2L & remember what vehicle (Make/model/year) the fan is out of?

Great job Bloopy. That looks like a Mark VII fan. Are you eventually going to run the wires in your electrical box through the holes you drilled, and then close it up?

How did you get the prob through the rad? ( sorry if this is a total newb question)

Wouldnt that cause it to leak?

The probe pushes through the fins just below the top hose so it gets the temp from the incoming water into the radiator. There are alot of kits available. I got mine from autozone for 35 dollars. Easy to install and works very well. I wired up the low side automatic and high side and off through a 2 position switch. I was using the stock alternator when I hooked it up for the first 2 months with no problems. I went to the alternator mod after because I am getting ready to mount a winch. The stock alternator didnt have any problems with only the fan mod and a decent stereo added. Great write up!

I made the openinging in the fins a little oversize and packed it with jb weld. the probe does not flop around and it will certainly transfer the heat measurement better.

I stuck a small philips screw driver in first to make a small hole for the probe to fit into. As for the jbweld that is a good idea ill have to try that.

Ill post pics of mine sometime this week. I matted the taurus 3.8L fan to the stock 2.5L jeep fan shroud to cover more surface area of the radiator. And plus I could use the stock bolt locations to hold it to the Rad. Ran it offroad this past Saturday. had no issues whatsoever. Only have the low speed on an adjustable thermostatic relay. And wired the 12 volt trigger wire to a rocker switch in the cab to be able to turn it off when I wanted. Works flawlessly and after adjustment keeps the water temp gauge between 180-210 always.

I don't off road much my self. Maybe once a month but still the electric fan is a good mod to do. Lets my jeep warm up faster for those cold mornings. Plus its easy as hell to do.
